the "you almost got shot" discount

We assumed this was the discount that was in play tonight when our waiter left our drinks off our tab at the chique Sports Bar in the new "Atlantic Station" in downtown atlanta (got to check it out people!).
A nice discount. How to get one for yourself? Well, it's a matter of luck I'm afraid. Just be there on the night that someone threatens to pull a gun and, thus, hundreds of wild people (including yourself and your two girlfriends) run frantically into street, just waiting to have to dodge bullets!
Where am I again?
